AUT OMOBILE-HEATER.

Specification of Letters Patent.

Patented July at, 39131.

Application filed January 14, 1909. Serial No. 472,315.

To all whom itmay concern Be it known that I, LEO A. lhtionn, a citizen of the United States, residing at Cincinnati. in the county of llamilton and State of Ohio. have invented certain new and useful Improvements in Automobile l'lcaters, of which the following is a specification.

My invention relates to improved means for heating automobiles.

One of its objects is to provide means whereby the heat from the engine exhaust may be utilized to keep the passengers cone fortable, during cold weather.

Another objectis to provide simple and ellicient mechanism for the above purpose, and efficient means for supplying. regulating and controlling the amount of heat as de; sired.

It further consists in certain details of form, combination and arrangement, all of which will be more fully set forth in the description accompanying the drawings, in which,

Figure l is a diagram in side elevation of an automobile with my improvements attached thereto. Fig. 9 is a dia ram in top plan, showing, the connection, arrangement and means for controlling the heat supply. Fig. 3 is a section through one of the controlling valves on line zv-ai of Fig. 2.

in the accompanying drawings, A, represents the hotly of an automobile of ordinary construction.

l5 represents the. engine or motor located at. the forward end of the body, A, which motor may he either a combustion engine consuming gasolenc or similar fuel, and exhausting a highly heated gas, or may be a steam engine exhausting steam.

C repre ents the usual engine exhaust pipe,v.'hich in combustion engines is usually provided with a mulllcr, c.

Resting on the. floor, (1., of the body in front of the respective seats, a, a 1 provide heaters, D, l), which are connected by means of a pipe, E, with the exhaust pipe, C. .t valve, FFServe-s to either close the. usual direct exit through the exhaust. pipe, and to force the exhaust through one or more of the l heaters, or when reversed to open the usual and direct. exhaust and to cut oil the passage through theheatcrs.

In order to provide for the passage of the, heated exhaust through either ot the heaters independently, or through both heaters, as

desired. I provide valves, G, H. The valve, G, is adapted to direct the exhaust as desired, into either heater, D, or D. The valve, H. is adapted to direct the heated exhaust from heater, D, into heater, D. by pipe, j and thence into a pipe, J, which leads to the exhaust pipe, C, or directlv bv a branch, j, into the pipe, J.- Thus th s exhaustmay be conducted first int-o heater, D, and thence to pipe, J, to apply heat only to heater, l). The exhaust may be caused to traverse and heat both heaters, D, and D, or the exhaust may he admitted only L0 heater, 1), through pipe, j, leaving heater, D, cold, or valve. F, may be employed to cut oil? the exhaust from both heaters, l), and l).

The connections leading the exhaust to and from the heaters may be variously arranged to accommodate the heater and its connections to variations in automobiles of ditlereut styles and manufacture. I preferably arrange the supply or intake so that it may be as free from obstruction as possible.

The mechanism herein illustrated and described is capable of considerable modification without departing from the principle of my invention.

Having described my invention, what I claim is.

1. In a mechanism of the character descrihed, a motor, a main motor exhaust contitl duit adapted topcrmit a direct escape oilithe motor exhaust, a branch conduit leading; from said main exhaust conduit adapted to direct the motor exhaust to heaters, a valve adapted to direct the motor exhaust to said main conduit or to said branch conduit wholly or in part, a plurality of heaters in position to impartheat to the car occupants,

2. in a mechanism of the character described, a motor having a motor exhaust passage through which the motor exhaust escapes from the motor under pressure, a

plurality of heaters, a conduit,leading from the exhaust passage of tlieinotoi' to said re spective heaters, a valve controlling admission of the exhaust to said conduit, a valve controlling the admissior ot exhaust; l'roiin valve to control the relative said conduit to either of said' heaters independently, a valve controlled conduit leading from one of said heaters.to and independent exit conduits leading from the respective heaters.

3. In a mechanism of the character described, a motor having a motor exhaust passage through which the motor exhaust est-a r from the motor underpressure, a pluraiity of heaters, a branch conduit leading Irom the motor flow of exhaust to said branch conduit, a

quantity of exhaust admitted to the respective heater, a

the other,

exhaust conduitto said respective heaters, a valve controlling the conduit leading from the first of said heaters to the second, a branch from said last named conduit constituting an exit conduit for said first heater, a valve to control the relative flow from said first heater to its exit conduit and to the second heater, and an independent exit conduit from said second heater. 7

In testimony whereof I have afiixed mv signature in oresence of two witnessez.
